2013-08-31* vm_insnhelper.h (CALL_SIMPLE_METHOD): change name of 'recv' argumentcharliesome
so that other variable names may be used when calling this macro git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42741 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-08-27vm_insnhelper.h: RBASIC_CLASSnobu
* vm_insnhelper.c (opt_eq_func): use RBASIC_CLASS() instead of HEAP_CLASS_OF(). * insns.def (opt_plus, opt_minus, opt_mult, opt_div, opt_mod, opt_lt), (opt_gt, opt_ltlt, opt_aref, opt_aset, opt_length, opt_size), (opt_empty_p, opt_succ): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42702 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-11-22* vm_insnhelper.h: partly revert r37631 (DTrace support).naruse
"vm usage information is always collected, so uncomment the functions." causes performance impact. [Bug #7370] Off course this revert disables related probes. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37796 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-11-12* probes.d: add DTrace probe declarations. [ruby-core:27448]tenderlove
* array.c (empty_ary_alloc, ary_new): added array create DTrace probe. * compile.c (rb_insns_name): allowing DTrace probes to access instruction sequence name. * Makefile.in: translate probes.d file to appropriate header file. * common.mk: declare dependencies on the DTrace header. * configure.in: add a test for existence of DTrace. * eval.c (setup_exception): add a probe for when an exception is raised. * gc.c: Add DTrace probes for mark begin and end, and sweep begin and end. * hash.c (empty_hash_alloc): Add a probe for hash allocation. * insns.def: Add probes for function entry and return. * internal.h: function declaration for compile.c change. * load.c (rb_f_load): add probes for `load` entry and exit, require entry and exit, and wrapping search_required for load path search. * object.c (rb_obj_alloc): added a probe for general object creation. * parse.y (yycompile0): added a probe around parse and compile phase. * string.c (empty_str_alloc, str_new): DTrace probes for string allocation. * test/dtrace/*: tests for DTrace probes. * vm.c (vm_invoke_proc): add probes for function return on exception raise, hash create, and instruction sequence execution. * vm_core.h: add probe declarations for function entry and exit. * vm_dump.c: add probes header file. * vm_eval.c (vm_call0_cfunc, vm_call0_cfunc_with_frame): add probe on function entry and return. * vm_exec.c: expose instruction number to instruction name function. * vm_insnshelper.c: add function entry and exit probes for cfunc methods. * vm_insnhelper.h: vm usage information is always collected, so uncomment the functions. 12 19:14:50 2012 Akinori MUSHA <knu@iDaemons.org> * configure.in (isinf, isnan): isinf() and isnan() are macros on DragonFly which cannot be found by AC_REPLACE_FUNCS(). This workaround enforces the fact that they exist on DragonFly. 12 15:59:38 2012 Shugo Maeda <shugo@ruby-lang.org> * vm_core.h (rb_call_info_t::refinements), compile.c (new_callinfo), vm_insnhelper.c (vm_search_method): revert r37616 because it's too slow. [ruby-dev:46477] * test/ruby/test_refinement.rb (test_inline_method_cache): skip the test until the bug is fixed efficiently. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37631 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-10-15* vm_insnhelper.h (CI_SET_FASTPATH): add new parameter `enabled'.ko1
If `enable' is 0 then CI_SET_FASTPATH() doesn't work. And add new configuration option OPT_CALL_FASTPATH. If this macro was defined by 0, then CI_SET_FASTPATH() doesn't work any more. * vm_insnhelper.c (vm_call_method): Pass `0' for `enabled' parameter of CI_SET_FASTPATH if this method is protected. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37197 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-10-14* vm_insnhelper.h CI_SET_FASTPATH: introduce new macroko1
`CI_SET_FASTPATH(ci, func)'. This macro set `ci->call' as `func'. `func' (ci->call) is called at the last of `send' (and `invokesuper') instruction. `CI_SET_FASTPATH' does not set `ci->call' when the method (stored in `ci->me') is `protected'. * vm_insnhelper.c (vm_call_method): use `CI_SET_FASTPATH'. After several checking (visibility, argc checking), the result of checking can be reused until re-definition of this method with inline method cache. Note that this optimization is now experimental. If you find any problem about it, please tell us. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37186 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-10-14* insns.def (send, invokesuper, invokeblock, opt_*), vm_core.h:ko1
use only a `ci' (rb_call_info_t) parameter instead of using parameters such as `op_id', 'op_argc', `blockiseq' and flag. These information are stored in rb_call_info_t at the compile time. This technique simplifies parameter passings at related function calls (~10% speedups for simple mehtod invocation at my machine). `rb_call_info_t' also has new function pointer variable `call'. This `call' variable enables to customize method (block) invocation process for each place. However, it always call `vm_call_general()' at this changes. `rb_call_info_t' also has temporary variables for method (block) invocation. * vm_core.h, compile.c, insns.def: introduce VM_CALL_ARGS_SKIP_SETUP VM_CALL macro. This flag indicates that this call can skip caller_setup (block arg and splat arg). * compile.c: catch up above changes. * iseq.c: catch up above changes (especially for TS_CALLINFO). * tool/instruction.rb: catch up above chagnes. * vm_insnhelper.c, vm_insnhelper.h: ditto. Macros and functions parameters are changed. * vm_eval.c (vm_call0): ditto (it will be rewriten soon). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37180 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-10-09* vm_core.h (rb_call_info_t): add new type `rb_call_inf_t'.ko1
This data structure contains information including inline method cache. After that, `struct iseq_inline_cache_entry' does not need to contain inline cache for method invocation. Other information will be added to this data structure. * vm_core.h (rb_iseq_t): add `callinfo_entries' and `callinfo_size' members to `rb_iseq_t'. * insns.def, compile.c: Use CALL_INFO instead of IC. * tool/instruction.rb: support CALL_INFO as operand type. * vm_insnhelper.c, vm_insnhelper.h: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37121 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-10-08* eval.c, gc.c, iseq.c, node.h, vm_insnhelper.c, vm_insnhelper.h,shugo
vm_method.c: rename omod and overlaid modules to refinements. * eval.c (hidden_identity_hash_new): renamed from identity_hash_new. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37117 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-10-04* vm.c (VM_COLLECT_USAGE_DETAILS): make new VM usage analysisko1
hooks (old macro name is COLLECT_USAGE_ANALYSIS). This feature is only for VM developers. (I'm not sure I can use `VM developers' (the plural form) in this sentence). If VM_COLLECT_USAGE_DETAILS is not 0, VM enables the following usage collection features: (1) insntruction: collect intruction usages. (2) operand: collect operand usages. (3) register: collect register usages. The results are stored in RubyVM::USAGE_ANALYSIS_INSN for (1, 2), RubyVM::USAGE_ANALYSIS_INSN_BIGRAM for (1) and RubyVM::USAGE_ANALYSIS_REGS for (3). You can stop collecting usages with RubyVM::USAGE_ANALYSIS_INSN_STOP(), RubyVM::USAGE_ANALYSIS_OPERAND_STOP(), RubyVM::USAGE_ANALYSIS_REGISTER_STOP() for (1), (2), (3) respectively. You can also change the hook functions by setting C level global variables `ruby_vm_collect_usage_func_(insn|operand|register)' for (1), (2), (3) respectively. See codes for more details. * tool/instruction.rb: fix macro names. * iseq.c (insn_operand_intern): make it export (used in vm.c). fix to skip several processes if not needed (pointer is 0). * vm_dump.c: move codes for collection features to vm.c. * vm_exec.h: rename macro and function names. * vm_insnhelper.h: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37085 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-09-26* insns.def: add new instruction `opt_empty_p' for optimize `empty?'ko1
method. Apply a patch proposed at [ruby-dev:46120] [ruby-trunk - Feature #6972] by Glass_saga (Masaki Matsushita). * compile.c (iseq_specialized_instruction), vm.c, vm_insnhelper.h: ditto. * id.c, template/id.h.tmpl: ditto. * test/ruby/test_optimization.rb: test for this changes. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37036 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-08-23* include/ruby/ruby.h: introduce flonum technique forko1
64bit CPU environment (sizeof(double) == sizeof(VALUE)). flonum technique enables to avoid double object creation if the double value d is in range about between 1.72723e-77 < |d| <= 1.15792e+77 or 0.0. flonum Float value is immediate and their lowest two bits are b10. If flonum is activated, then USE_FLONUM macro is 1. I'll write detailed in this technique on https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/Flonum_tech * benchmark/bmx_temp.rb: add an benchmark for simple Float calculation. * gc.c (id2ref, rb_obj_id): add flonum Float support. * include/ruby/intern.h: move decl of rb_float_new(double) to include/ruby/ruby.h. * insns.def, vm.c, vm_insnhelper.c: add flonum optimization and simplify source code. * vm_insnhelper.h (FLONUM_2_P): added. * marshal.c: support flonum output. * numeric.c (rb_float_new_in_heap): added. * parse.y: support flonum. * random.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36798 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

vm_insnhelper.c, vm_insnhelper.h, vm_method.c: add klass to rb_control_frame_t to implement super correctly. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36595 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-06-11* vm_core.h: remove lfp (local frame pointer) and renameko1
dfp (dynamic frame pointer) to ep (environment pointer). This change make VM `normal' (similar to other interpreters). Before this commit: Each frame has two env pointers lfp and dfp. lfp points local environment which is method/class/toplevel frame. lfp[0] is block pointer. dfp is block local frame. dfp[0] points previous (parent) environment pointer. lfp == dfp when frame is method/class/toplevel. You can get lfp from dfp by traversing previous environment pointers. After this commit: Each frame has only `ep' to point respective enviornoment. If there is parent environment, then ep[0] points parent envioenment (as dfp). If there are no more environment, then ep[0] points block pointer (as lfp). We call such ep as `LEP' (local EP). We add some macros to get LEP and to detect LEP or not. In short, we replace dfp and lfp with ep and LEP. rb_block_t and rb_binding_t member `lfp' and `dfp' are removed and member `ep' is added. rename rb_thread_t's member `local_lfp' and `local_svar' to `root_lep' and `root_svar'. (VM_EP_PREV_EP(ep)): get previous environment pointer. This macro assume that ep is not LEP. (VM_EP_BLOCK_PTR(ep)): get block pointer. This macro assume that ep is LEP. (VM_EP_LEP_P(ep)): detect ep is LEP or not. (VM_ENVVAL_BLOCK_PTR(ptr)): make block pointer. (VM_ENVVAL_BLOCK_PTR_P(v)): detect v is block pointer. (VM_ENVVAL_PREV_EP_PTR(ptr)): make prev environment pointer. (VM_ENVVAL_PREV_EP_PTR_P(v)): detect v is prev env pointer. * vm.c: apply above changes. (VM_EP_LEP(ep)): get LEP. (VM_CF_LEP(cfp)): get LEP of cfp->ep. (VM_CF_PREV_EP(cfp)): utility function VM_EP_PREV_EP(cfp->ep). (VM_CF_BLOCK_PTR(cfp)): utility function VM_EP_BLOCK_PTR(cfp->ep). * vm.c, vm_eval.c, vm_insnhelper.c, vm_insnhelper.h, insns.def: apply above changes. * cont.c: ditto. * eval.c, eval_intern.h: ditto. * proc.c: ditto. * thread.c: ditto. * vm_dump.c: ditto. * vm_exec.h: fix function name (on vm debug mode). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36030 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-06-04* vm_insnhelper.h: remove magical code "lfp[0] & 0x02".ko1
Current VM doesn't use this bit. * vm_core.h (RUBY_VM_GET_BLOCK_PTR): added. * eval.c (rb_block_given_p): use RUBY_VM_GET_BLOCK_PTR(). * vm_eval.c (rb_f_block_given_p): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@35908 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
